Question	—	Can I improve internal combustion engine efficiency by slightly changing vacuum permittivity? Energy released in an exothermic reaction depends on bond energies of reactants and products. Since molecular bonds are electric in nature, at the first glance, increasing Coulomb's force should increase bond energy and, thus, combustion energy. With that in mind, here is the setup I'm considering: ... (more)	—	about 5 years ago
Question	—	If someone dropped a black hole into the Sun, when and how will we notice it? Suppose someone dropped a black hole into our lovely Sun a few million years ago. It was big enough (far bigger than that) from the start to eat matter faster than radiating it away, and kept growing and growing. At some time in the future, it would consume most of the star and the change would be ob... (more)	—	about 5 years ago
